Abstract In Wireless Sensor Network (WSN), because battery and energy supply are
constraints, sleep scheduling is always needed to save energy while maintaining
connectivity for packet delivery. Traditional schemes have to ensure high duty cycling to
ensure enough percentage of active nodes and then derogate the energy efficiency. This
paper proposes an RFID based non-preemptive random sleep scheduling scheme with
stable low duty cycle. It employs delay tolerant network routing protocol to tackle the
frequent disconnections. A low-power RFID based non-preemptive wakeup signal is used
to confirm the availability of next-hop before sending packet. It eliminates More >
